IBM ThinkPad t43: Why can't I turn on my laptop

Sun, 04 May 2025 07:11:30 -0700

So I have this laptop for sometime now before it used to work but now it don't seem to turn on at all. I've tried to charge it to see if it was a low battery issue but there's still no sign of it even charging. So can anyone tell me what the issue is and if it is fixable or not? If it is please briefly guide me with it too.

IBM ThinkPad t43: T43p will not POST

Mon, 14 Feb 2022 02:02:24 -0700

Hello. I have (found) a T43p.

It came with a 2878 dock and a battery. I am unable to find a charger that fits the 2878 dock but is able to find one that fits the laptop itself. The battery is able to be charged by the device (the battery LED was amber then it turned green), and when unplugged you can hear the coil whine of the battery/motherboard circuit. However, no matter what I do the machine will not turn on (the power LED will not come on)

And thus I took apart, cleaned and reassembled every part. The symptoms remain, so I probably didnt made it worse.

Note that my unit come with a fingerprint sensor, and that the hard-drive is missing. However, I do not think either of these will prevent the machine from powering up and post. I put a Win NT workstation disk in, just in case.

It come with two stick of Hynix DDR2 memory, but then, again, this should not prevent it from powering up.

The machine come with a full set of Centrino (north, south, CPU, wireless), and I think it is the 900 Series Sonoma Pentium M Dothan “variant”. It also come with ~~AMD~~ ATi FireGL Mobile.
